DAZ3D Iray, MAC and CUDA

Hi everyone,

I have an 2009 imac, dual core and I'm suffering while rendering IRAY, it takes much time so I decided its time to upgrade.

A very nice guy said a new imac 5k, comes with a good NVIDIA GeForce GT 750M 1GB, GDDR5. I'm wondering if DAZ3D would use GPU as an option, instead of CPU. And if my renders would be fast enough.

Maybe if I install a CUDA driver?


thank you!

    Your guy might be nice, but he's a little confused. The 5K iMacs all have AMD video that are not compatible with iray. The non 5K iMac has nvidia with will work with iray.

    The system is compatible with Iray, it just won't take advantage of the GPU.

    thank you.

    the question is

    would a intel i7 CPU be as fast as a Nvidia GT 550M GPU when rendering IRAY?

    Im deciding between a mac 4k (i7) without NVIDIA and a simple mac (i5) with Nvidia.

    so hard decision.

    No...the CPU render will be slower than the GPU render, by a large margin...but, you will be able to render much larger scenes with CPU, than the GPU, because scene size is limited to the DEDICATED memory on the video card. If it doesn't fit, then it falls back to CPU rendering, so you would lose any speed advantage, anyway.

    You might want to look into an old model (pre-trashcan) Mac Pro. You can still find them, and at quite reasonable prices (for a Mac). With that you can put whatever memory and disk is appropriate for your needs, and still use a modern Nvidia GPU. I installed a GT 980 in mine when DAZ introduced 4.8, and I've been quite happy with it. I got my card from MacVidCards.com. They reflash consumer PC cards with Mac firmware.
